SIDE-HILL PLOW.

SPECIFICATION forming part of Letters Patent'No. 420,647, dated February4, 1890.

Application iilediirrh ll, 1889.

To all whom it may concern.-

Be it known that we, HARRY VVIARD and JAMES L. J UDD, of Syracuse, inthe county of Onondaga, in the State of NewYork, have invented 'new anduseful Improvements in Side- I-Iill Plows, of which the following, takenin connection with the accompanying drawings, is a full, clear, andexact description.

This invention relates to the class of plows designated reversible orside-hill plows; and the invention consists in an improved constructionand combination of certain auxiliary devices connected to the plow, ashereinafter fully described, and specifically set forth in the claims.

In the annexed drawings, Figure 1 is a side elevation of a plowembodying our improvements. Fig. 2 is a rear end view of the same. Fig.3 is an enlarged detached side view of that portion of the jointer-shankto which the stop is attached. Fig. a is an inverted plan view of thatportion of the strap which is provided with the co-operating stops. Fig.5 is an end view of said strap. Fig. 6 is a detached face view of thethree-armed brace. Fig. 7 is aside view of the same. Fig. Sis a furtherenlarged longitudinal sectional view of one of the portions of thethree-armed brace to which one of the wear-blocks is attached, and Fig.9 is a perspective View of the connection of the clevis -shifting leverwith the notched cross-bar.

Similar letters of reference indicate corresponding parts.

A denotes the standard of the plow; B, the mold-board, which is adaptedto be swung toward either side of the plow in the usual and well-knownmanner.

O represents the jointer, whose shank C passes obliquely through thebeam A and is pivotally connected to the top thereof by means of a blockm, pivoted to the beam and having secured to it the jointer-shank, saidblock being turned automatically with the reversing of the mold-board bya rod 01., connecting said block with the usual three-armed brace b b b,as shown and described in our pending application for Letters Patent,Serial No. 307,819, filed April 19, 1889, or by other suitable andwell-known means. By the aforesaid turning of the block m the jointernewed when necessary, and we Serial No. 317,226. (No model.)

is turned on its axis, so as to operate on the same side with themold-board B.

In order to sustain the jointer more eifectually in its said operativepositions,.we employ suitable stops, respectively, on the beam anddirectly on the jointer-shank, and preferably on the under side of thebeam and adjacent side of the jointer-shank. Said stops we preferablyform by providing the jointer-- shank C with a lug Z on its side, whichlug projects into a recess 1', formed in the side of the eye If in thestrap t, through which the jointer-shank passes, said strap beingadjustably secured to the under side of the beam, as shown and describedin our prior application for Letters Patent hereinbefore referred to.The recess 1' is of sufficient length to allow the jointer-shank to beturned to bring the jointer into its requisite operative position, ashereinbefore stated, and when in said position the lug Z rests againstone of the end walls of the'recess r, and thereby sustains thejointer-shank so as to hold the jointer O in its requisite angle inrelation to the line of draft. 4

Practical experience with plows of the class to which our inventionpertains has disclosed the fact that it is difficult to obtain andmaintain accurate engagement of the duplex hook at with the three-armedbrace 17 b Z7, so as to firmly hold themold-board in its proper position, owing to the liability of warping of the casting while coolingthe same, or some vari* ations in the attachment of the several parts,and the wear and abrasion of the engaging part-s. To overcome thisdifficulty We connect to the three-armed brace wear-blocks (Z d, withwhich the duplex hook engages, said wear-blocks being detachable andreadily repreferably arrange said blocks adjustable, so as to take upany play or lost motion between the engage ments thereof with the duplexhook a. Said adjustable attachment consists in providing each of thearms I) b of the three-armed brace with transverse shoulders c c, andwith a transverse slot 6 between said shoulders and inserting the wearblock d between the shoulders c c and securing it in position bya boltf, passing through said block and through the slot 6, and provided witha head and nut,

by which to clamp the wear-block cl in its requisite position. Theattachment of the wear-blocks is shown in detail in Figs. 6, 7, and 8 ofthe drawings. The slots 6 6 allow the wear-blocks (Z (l to be shiftedlaterally on the three-armed brace, so as to engage with the duplex hookat at the proper time and firmly hold the mold-board in its position. Itis obvious that in reversible or side-hillplows which do not employ thethree-armed brace 11 l) b the aforesaid wear-blocks at (Z are to beattached to such part of the plow with which the duplex hook a engages.

h represents the clevis-shifting lever, which is attached to a rearwardextension of the top portion of the clevis I, and is extended rearwardandlies across the top of the notched cross-bar g, which ties the freeends of the handles-n n to each other. The rear 'endportion isattenuated to render it elastic, and is bent forward into a U-shapedspring-loop p, the free end of which lies across the under side of thecross-bar g, and serves to hold the lever h in its engagement with oneof the notches of the bar g.

To turn the clevis I when desired the operator takes hold of the rearend of the lever it, above the loop p, and lifts said lever out of thenotch of the bar g, and after swinging said lever laterally into itsrequisite position he allows it to drop into the proper notch of the bar9, which holds the lever in its adjusted position.

In order to guard against excessive strain on the spring-loop p inlifting the lever, as aforesaid, we employ a suitable stop 1', whichextends across the spring-loop, as best seen in Fig. 0 of the drawings,in which it is represented in the form of a clevis attached to the leverh, and receiving through it the forward extension or free end portion ofthe springaloop, with sufficient vertical play between them to merelyallow the lever 71 to be raised out of the notch of the bar g.

Having described our invention, what we claim as new, and desire tosecure by Letters Patent, is-

1. In combination with the beam and jointer pivotally connected to thetop of the beam, the strap t, connected to the bottom of the beam andprovided with the eye 6 for the jointer-shank, and with the recess 7 inthe side of the said eye, and the lug Z on the side of the jointer-shankprojecting into the recess 1, substantially as described and shown.

2. In combination with the standard A, pivoted mold-board B, and duplexhook at, the three-armed brace b b 1), formed with transverse shouldersc c and transverse slots 6 6 between said shoulders, the wear-blocks (l(I, inserted between said shoulders, and bolts ff, passing through thewear-blocks and slots of the brace, substantially as described andshown.

3. The combination,with'thenotched crossbar 9 and the lever 7L, havingits rear end lying across one side of said notched bar and terminatingwith a forwardly-bent spring-loop lying with its free end across theopposite side of the notched bar, of a stop extending across the saidspring-loop to protect the same from excessive strain in raising thelever out of engagement with the notched bar, substantially as setforth.

t. In combination with the standard A, pivoted mold-board B, and duplexhook a, wear-blocks detachably secured in position to engage with thesaid duplex hook and thereby sustain the mold-board in its adjustedposition, as set forth.

In testimony whereof we have hereunto signed our names this 9th day ofJuly, 1889.
